Answer:
102º
Step-by-step explanation:
So you know that ABC is an Isosceles triangle as AB=AC therefore, angle ABC is equal to angle ACB.
You also know that even though it doesn't look like it, ABP is an equilateral triangle as AB, AP and BP are equal so all those angles must equal 60º.
So:
ABC = 60 - 21 = 39º
and since ABC= ACB
ACB also equals 39º.
Because angles in a triangle add to 180º, BAC is consequently:
180- (39+39) = 180 - 78 = 102º
BAC = 102º
Mr.simpson is constructing a swing set for his children. He measures that the patform will be 7 feet high and would like to attach an 11-feet slide. How many feet away from the base will it be set? (Round to the nearest tenth.)
Answer:
8.5 ft
Step-by-step explanation:
We assume that Mr. Simpson can model his construction using a right triangle with leg 7 ft and hypotenuse 11 ft, as shown in the attachment. Then the other leg can be found using the Pythagorean theorem.
__
a² +b² = c²
x² +7² = 11²
x² = 121 -49 = 72
x = √72 = 6√2 ≈ 8.485 . . . . feet
The slide will be set about 8.5 feet away from the base.

The first step that we must take before attempting to solve a problem is to understand what the problem statement is asking from us and what is given to us to help accomplish that goal. Looking at the problem statement, it asks us what the probability of choosing a vegetable is. We are given information about how many dishes of each type of food there is out of 10 dishes.
The next step that we need to do is to collect the total amount of vegetable dishes that have been listed in the problem statement along with the total amount of dishes. We know that there are 10 covered dishes and that there are 2 broccoli and 2 carrot which adds up to 4 vegetable dishes.
Now that we have that information we can move onto the final part which is to determine the probability of choosing a vegetable dish. We can do this by dividing the total amount of vegetable dishes from the total amount of dishes.
Determine the probability
[tex]\textsf{probability = (vegetable dishes) / (total dishes)}[/tex][tex]\textsf{probability = (4) / (10)}[/tex][tex]\textsf{probability = (4/2) / (10/2)}[/tex][tex]\textsf{probability = (2) / (5)}[/tex]Therefore, looking at the options that best matches the answer that we got we can confidentially say that it is option A, 2/5.
[tex]\huge\text{Hey there!}[/tex]
[tex]\text{Your equation: }\rm{\dfrac{number\ of\ the\ vegetables (the\ carrots\ \& \ the \ broccolis)}{total\ meals\ you\ have\ all\ together} = probability}\\\\\rm{\dfrac{2\ carrots + 2 \ broccolis}{10\ meals} = probability}\\\\\text{2 + 2 = \boxed{\mathbf 4} , right?}\\\\\rm{\dfrac{4}{10} = probability}\\\\\rm{\dfrac{4\div2}{10\div 2} = probability}\\\\\rm{\dfrac{2}{5} = probability}\\\\\\\huge\text{Therefore, your answer should be: \boxed{\mathsf{\dfrac{2}{5}}}}\huge\checkmark[/tex]

You must be at least 48 inches tall to ride an amusement park and your little sister is 39 inches tall. How many inches in must she grow before she may ride the ride?
Answer:
9 inches
Step-by-step explanation:
you have to be at least 48 inches so the shortest person that can ride it is 48 and she is 39 so you minus the 39 from 48 and you will get the inches she needs to grow

Which of the following equations are linear functions? Explain how you got your answer.
Select the three linear functions.
A. y = x to the power of 2 - 1
B. y = 2x + 1
C. y = 1/2x - 5
D. y = 1/3x to the power of 2
E. y = -x
Answer:
B, C, and E
The reason B, C, and E are the answer's is because the equation of a linear equation is y= mx+b. B, C, and E are written this way. We can eliminate A and D because They are quadratic equations, because the X is squared.

Given the function f(x)=5x+4, find f(x-2)
Answer:
5x - 6
Step-by-step explanation:
f(x) = 5x + 4
f(x-2) = 5(x -2) + 4
f(x-2) = 5x - 10 + 4
f(x-2) = 5x - 6
I hope this helps!
Answer:
5x - 6
Step-by-step explanation:
Plug in x-2 to the function:
f(x - 2) = 5(x - 2) + 4
= 5x - 10 + 4
= 5x - 6

Dale polled the 2 fastest swimmers on the swim team.
Is this sample of the swimmers on the swim team likely to be representative?
Answer as Yes or No
Reason:
Dale is biased toward the two fastest people in the group, but is leaving out the rest of the swimmers who may not be so fast. The people left out may be very distant from the top two swimmers. Therefore, Dale has not picked a representative sample.
As an example with numbers, let's say we had these average speeds in mph: {1, 2, 3, 4, 20, 30}. Of course these are just hypothetical examples and not based on actual realistic speeds; however, the example should still suffice.
That data set shows the average is closer to 2 and 3 than it is to 20 and 30. Dale polling the fastest people greatly skews the mean larger than it should be.
To get a better more representative sample, Dale should randomly pick 2 people regardless if they are the top two swimmers or not. He can pick the names out of a hat, or use a computer program to generate random numbers.

Answer the following about 4,240/8 estimating.
Answer: The answer to the equation 4,240/8 = 530
Step-by-step explanation:
4,240 divided by 8 = 530
4,000 divided by 8 = 500
4,800 divided by 8 = 600
(For part B 500 would be an underestimate of the answer to 4,240/8 and 600 would be an overestimate of 4,240/8)

4 The temperature in Stockton was 83°F. The temperature in New York was –5°F. How much hotter was the temperature in Stockton?
Answer:
It was 88°F hotter in Stockton.
If it was 0°F in New York, Stockton would have been greater by 83°F; as it is -5, add 5 to 83.
As the problem is subtraction, negative.
If the quantity is in negative, like -5, -7, -120; you have to add.

What is the slope of the table.
Answer:
slope is -5
Step-by-step explanation:
The formula for slope is:
m = (y2 - y1)/(x2 - x1)
m = slope
y2 = y-coordinate of second point
y1 = y-coordinate of first point
x2 = x-coordinate of second point
x1 = x-coordinate of first point
We can choose our first and second points as any points on the table, but we will choose the first andd second points which are (-5,10) and (-3,0).
y2 = 0
y1 = 10
x2 = -3
x1 = -5
m = (0-10)/(-3-(-5))
m = (-10)/(-3+5)
m = (-10)/(2)
m = -5
